Application August 15, 1946, Serial No. 690,686

1 Claim. 1 This invention relates to new and useful improvements andstructural refinements in smoothingplanes, and the principal object ofthe invention is to provide a device of the character herein described,such as may be conveniently and effectively employed for preventing theshavings from accumulating and obstructing the chip passage in thevicinity of the cutting knife, as is frequently experienced when usingplanes of conventional design.

A further object of the invention is to provide a device for guiding thechips or shavings, which is self functioning in operation and which maybe applied to both new planes, or alternatively, as an attachment forplanes already in existance.

Another object of the invention is to provide a chip guiding devicewhich is simple in construction and operation.

An additional object of the invention is to provide a chip guidingdevice which may be readily disassembled for purposes of inspection orrepair.

With the above more important objects in view, and such other objects asmay become apparent as this specification proceeds, the inventionconsists essentially of the arrangement and construction of parts asillustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a smoothing plane, showing the inventionin situ therein Figure 2 is a top-plan view of the same Figure 3 is across-sectional view, taken substantially in the plane of the line 3-3in Figure 2, and

Figure 4 is a cross-sectional view, taken substantially in the plane ofthe line 4-4 in Figure 3.

Like characters of reference are used to designate like parts in thespecification and throughout the several views.

Referring now to the accompanying drawings in detail, the inventionconsists of a chip guiding device designated generally by the referencecharacter 5 and may be used in association with a smoothing plane 6 ofmore or less conventional design. This plane customarily includes in itsconstruction a substantially U-shaped, channellike base 1 formed with achip passage 8 and provided with a suitable cutting knife 9. The cuttingedge portion of this knife extends into the passage 8, as will beclearly understood.

The essence of the invention resides in the provision of the chipguiding device 5, as aforesaid, the same embodying in its construction apin l0 secured in suitable apertures I I, I2 formed in the sides 13 ofthe base 1. One of these apertures (I2) is screw-threaded to receive athreaded portion 14 formed at one end of the pin, the remaining end ofthe pin being provided with a diametrically extending kerf [5. It willbe noted that in this manner, the pin l0 may be firmly and securelymounted in the base I.

It will be also observed that the pin extends transversely of thepassage 8 forwardly of the knife 9 and a roller 16 is rotatablypositioned on the pin, as is best shown in Figure 3. The roller l6extends nearly the full width of the passage 8 and the underside of theroller is substantially flush with the under-surface [6 of the base 1.

An upright web I! is provided, preferably by integral formation, betweenthe sides I3 of the base 1, and a deflector block I8 is secured to theweb ll by means of a plurality of suitable screws IS. The block I8 isconfigurated substantially as shown and extends substantially the fulllength of the roller I5.

It will be noted that the deflector block 18 is disposed adjacent theroller l5 and that a surface 20 thereof is concaved complementarily tothe lateral surface of the roller, as is best shown in Figure 3.

When the invention is placed in use, the plane 6 is manipulated in thewell-known manner and the chips or shavings originating at the cuttingedge of the knife 9 will be guided upwardly by the roller l5 anddeflected by the block l8, so that they will not accumulate and obstructthe passage 8.

It is believed that the advantages and use of the invention will beclearly understood from the foregoing disclosure, and accordingly,further description thereof at this point is considered necessary.

While in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.

What I claim as my invention is:

In a smoothing plane including a body portion comprising a flat base andperpendicular side walls, said base having a transverse chip receivingopening, a forwardly and downwardly inclined blade secured to said bodyportion and having its cutting edge positioned in said opening and aperpendicular wall rising from said base disposed forwardly of saidopening; a chip guiding device mounted on said body portion and2,497,761 v v 3 a i comprising a transversely extending pin detach- 7REFERENCES CITED ably secured to the sides of said body portion Thefollowing references are of record in the roller mounted on said pin andreceived in said file of thls patent. opemng, the surface of the rollerbeing substantially flush with the outer surface of the base, 5 UNITED SPA ENTS an elongated substantially triangular block (142- Number NameDate tachably secured to said perpendicular wall, said 189967 TierneyHHHHU Apt 24' 1877 l k havin a concaved recess provided in one 1,499,655:Hargis 1, 1924 face thereof, the Wall of said recess embracing a partof the cylindrical surface of said roller, said 10 recess extendingthroughout the length of said roller.
